I built an RGB thermometer with its own web interface that can control home appliances based on temperature changes

Extract data items from a mmWave sensor, train a NN to diagnose pipeline defects, and inspect results w/ deformed pipe images on a web app.

A cheap, fully 3D-printed, Raspberry Pi Zero 2 W–driven robot dog with 14 DOF that actually walks, trots, and looks around on a wide-angle camera, built entirely from off-the-shelf parts and a lot of trial, error and swearing.

An educational CAD and manufacturing project developed by high school students

This is a 3D printable boat, used to support two 3V DC motor and one Servo motor to turn the sail.

Lightweight ESP32-based IoT module for remote data logging enabling the collection and upload of 3D printing statistic values to a cloud server, as well as displaying them locally on a dedicated display. The project also involves extending the Marlin project by adding a custom G-code command at the firmware level.

A fully engineered obstacle-avoidance robotic car featuring a complete SolidWorks design, 6-sensor perception, and Arduino-based control—built as a foundation for future autonomous navigation modes.

Diyas are the heart of major Indian festivals, most notably Diwali, the "Festival of Lights." Lighting rows of diyas during Diwali symbolizes the victory of Lord Rama over Ravana and the welcoming of prosperity and Godess Lakshmi (the goddess of wealth). Tired of oily Diyas? In this tutorial, I will show you guys how I created these super simple 3D printed Diwali Diyas which are safe, non greasy, reusable, easy to make and will last forever.

The Linear Keyboard provides the amazing feel of a full mechanical keyboard and allows you to take its small form factor on the go!

A 3 dof arm robot is a personal assistant robot for lab and an added hand for hardware engineers in a lab to pick, place and hold in a collaborative woring space.

A complete DIY 3D printer designed and modeled in SolidWorks 2025, inspired by open-source CoreXY and Cartesian architectures. This project demonstrates mechanical design, motion system modeling, and mechatronic integration — providing a fully parameterized 3D model and educational documentation for engineers and makers interested in additive manufacturing

A modern DIY wooden speaker that looks clean, sounds big, and is fun to build.

ReMIX35 is an open-hardware reinterpretation of the Prusa MK3.5 electronics — a fully community-driven mainboard designed to bring modern 32-bit performance and transparent engineering to the iconic MK3S/+ platform. Built around the STM32F427 microcontroller and Trinamic TMC2130 drivers, ReMIX35 ensures binary compatibility with the original Prusa firmware while staying true to open design principles. What began as a reverse-engineering study evolved into a complete hardware rebuild — adapting the xBuddy form factor to the classic Einsy RAMBo layout, analyzing every subsystem, and testing the board extensively on real printers. The result is not just an upgrade, but a dive into the engineering behind one of the most successful open 3D printer architectures — a project built by and for the community.

This is a 3D-printed, self-watering planter designed specifically for busy students and professionals. It solves the number one problem of indoor plant care—underwatering from neglect and overwatering from panic—using a passive wicking system to give plants consistent moisture. It's a low-maintenance, customizable, and 3D-printable solution to help anyone keep their plants alive and thriving, even in a busy environment.

For this Halloween, I'm fusing the creative blocky world of Minecraft with the spooky glow of the colorful RGB LEDs in a fun and simple Halloween project.

The Quadcopter Y1101 is a 3D SolidWorks–modeled, high-aerodynamic-resistance racing drone designed for precision, speed, and stability. This project merges simulation-driven design with hands-on fabrication, using 6-inch NACA-M18 propeller blades to maximize lift efficiency and maintain stability at high flight velocities. However, the blade design is fully parametric and customizable, meaning the propeller geometry can be modified or redesigned based on the research methodology being pursued. This allows engineers and researchers to explore performance variations across different airfoil profiles, pitch angles, and chord lengths, enabling targeted optimization for speed, stability, and flight precision in both racing and research applications. The Y1101 was created as a 3D-printable prototype platform for testing aerodynamic performance and control algorithms, bridging the gap between simulation-based design and real-world racing drone prototyping.

Precision meets simplicity- a fully engineered sheet metal enclosure designed for performance, manufacturability, and modern aesthetics.
